Application filed May 24, 1

To all whom it may concern: Be it known that I, AUcUsTUsF. DONALD- sON, a citizen of the United States, and a resident of Toledo, in the county "of Lucas and. State of Ohio, have inventeda certain new and useful Babbitting-Machine'; and-I do hereby declare the following'to .be a full,' clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencehbeil'lg imam the accom pa'rt-of-thisspecification.f I I Myinvention-has for its 0 J provide in connection with a babbittinginaehine-a' means whereby the Babbitt metal may be I cooled at a certain definite'rate to-insure cohesion of the metal .jvitlifthe bushing and to regulate the inetalflow tofobviate-the efl'ects of metal contraction gdue to cooling and withdrawal from 'the""l 1'ot babbitted bushing .The invention maybe contained in struc- 'tures of dift'erentforms. To illustrate constructions contamin'g'my nvent1on I have selected one of such str'u'ctures and shall describe it hereinafter. The structure selected illustrated in the accompanying drawcore.

tend from the housing 3. One end is provided with the weight 13, while the other end is provided with a pivoted dog lithat is connected to' the edal 15. The dog 14: engages under the ange 16v formed on the front of the upper edge of the housing 3 "to I hold the weight 13 up and to release the I pressurepf the lever 11 'and the cams 10 on .the pins 7. By movement of thepedal 1'5 towardthe machine the lever is released and the weight 13 operates to lift the pins 7 that ride on the-cams '10 a;nd to raise the cap plate"5.' The;bushing 17 that is to be babbitted is placedon-the cap plate 5 and into a recess 18. The recess 18 maybe cut so as to form a shoulder 19 on which the lower end of the bushing is placed leaving a space between the bottom of the recess 18 and the I lower end -of the bushing .17. ,The upper end of the bushing 17 fits a similar plate 20 which is also provided with a recess 21 that has a shoulder 22 against which the I upper end of the bushing. 17 is pressed by the operation of-the-lever 11 and the weight 13. "The loweg'ledge' of the recess between the face "of the plate 20.and the shoulder 22 is beveled so-as to automatically center the bushing 17 with reference to the plate 20 when it is raised'so as to press against the shoulder 22.-'- The'-plate 20 is supported in abracket 23 which-is bolted to the face plate 2 by meansofthebolts 24:. The plate 20 to ether withparts of the bracket 23 forms a hopper 25 into 'which Babbitt metal may be poured when the bushing 17 has been placed in position andclamped between the plates 5 and 20. They also form an overflow trough 26 from-which the metal maybe gathered when the core 27 israised into the 'bushing 17 to eliminate the surplus of the metal that is poured into the bushing :17 to heat it to the-proper babbittiug temperature as well as a rack 29.: The lower-end of the core is to give it the babbitt coating or I providedwith aflange 30 and a boss 31. The boss 31 fits into a recess 32 of the rack I through the valve 37 at the proper times and for the proper length of time. The water will pass up through one of the passageways 34 into the core 27 and out through the other passageway 34 and through the other pipe 36 when the valve 37 is open. The rack 29 moves in the housing 3 and is provided with the teeth 38. The pinion 39 operates to move the rack up and down in the housing 3 and to raise and lower the core 27 into and outof the bushing 17 The pinion 39 is located on the shaft 40' that is located in the housing 3. The cogwheel 41 is also keyed to the shaft 40 and is operated upon by the pinion 42 located between the plate 43 and the housing 3. The pinion 42 is connected to the crank 44. R0- tation of the crank 44 causes rotation of-the pinion 39 and upward movementof the rack 29 and the core'27. The bushing 17 r is, in the operation of the machine, first clamped between the plates 5 and 20 and then filled with the babbitting metal until the bushing is raised to the same temperature as the Babbitt metal whereupon the core 27 is raised and the surplus of the Babbitt metal, that is, other than that that is located intermediate the core and the bushing and which forms the babbitt layer and possibly some that enters the recesses 18 and 21, is pushed upward from the bushing 17 out through the lower part of the hopper 25 into the trough 26 from whence it may be collected by a suitable receptacle, such as a dipper. The bushing 17 quite accurately fits in the recesses 18 and 21 and against the shoulders 19 and 22. The boss 60f the plate 5,be-

ing somewhat loosely placed in the upper end of the housing 3 and the rounded ends of the pins 7 permitting a slight tilting movement of the plate 5 causesthe ends of the bushing 17 to snugly fit the plates 5 and 20 notwithstanding a slight irregularity of the ends of the bushings 17 or notwithstanding any slight deviation from parallelism between the planes of the upper and lower edges or end surfaces of the bushing 17. The core 27 quite accurately fits the plate 5 and will pass up through an opening in the plate 20 that extends tothe recess 21 and conununicates with the hopper 25. The core 27 quite accurately fits the opening thus formed in the plate 20. The wall of the assenteopening in the plate 20, however, is provided with the niches 46 which permit communication of the molten metal in the hopper 25 after the core 27 has been raised,- with the metal that surrounds the core 27 'in the bushing 17 and feeds to the metal within the bushing molten metal in the hopper 25 during the cooling operation of the metal in the bushing.-

Vvhen the metal has been properly cooled,

by the regulation of the fiow of the cooling medium through the valve 37, the core 27 is lowered. .This is done by the operationof the lever 47 Which may be made of any length but it is shown as broken off for purposes of illustration in the figures. The lever 47 is provided with four fingers 48 that fit over the shaft 40 and on each side of the ratchet 49 which is secured to the shaft 40. The lever 47 is provided with a link 50 which is pivotally secured in the ear 51 so that as the lever 47 is raised the link 50 will slip over the ratchet 49 and engage with the teeth. Downward movement of the lever will cause rotation of the ratchet 49 and rotation of the pinion 39 so as to draw the rack 29 and the core 27 downward until the core 27 is drawn from the bushing whereupon the bushing 17 may be removed from the machine and trimmed by any of the methods well known.

The rack 29 may be sustained in its lowermost position by means of the bracket 56 having an adjustable arm 57 that is secured in position by means of the bolt 59. The arm 57 is provided with a bolt 58 that abuts the bolt 28 and thus limits the downward 'movement of the rack 29.
